Description

Technical Field

[0001] The utility model relates to the technical field of base structures and discloses a base structure of a robot welding machine. Background Art

[0002] A robotic welding machine is an automated device used to perform welding operations in industrial production. It combines robotic technology with welding techniques to improve welding quality and production efficiency while reducing labor costs. The robotic welding machine base typically refers to the base platform or support structure on which the industrial robot is mounted during welding operations.

[0003] The design and manufacture of robotic welding machine bases require consideration of multiple factors to ensure efficient and safe welding operations. Existing bases typically have a fixed area, making it impossible to adjust the load-bearing area as needed, limiting overall stability. If the base cannot adjust its load-bearing area as the load changes, the lower support base may become loose during prolonged operation of the robotic welding machine.

[0004] Therefore, a robot welding machine base structure capable of increasing stability is needed. Utility Model Content

[0005] In order to overcome the disadvantage that the existing base area is usually fixed and the force-bearing area cannot be adjusted according to needs, which limits the improvement of overall stability, if the base cannot adjust its force-bearing area as the load changes, then during the long-term operation of the robot welding machine, the lower support base may become loose. The utility model provides a robot welding machine base structure that can increase stability.

[0006] The technical solution of the utility model is: a robot welding machine base structure, including a lower supporting base, a supporting plate and an upper supporting base, two supporting plates are slidingly arranged inside the lower supporting base, and an upper supporting base is slidingly arranged on the lower supporting base, and also includes a connecting frame, a bidirectional screw and a first guide rod, the front and rear sides of the support plate are fixedly connected to the connecting frame, the front side of the lower supporting base is fixedly connected to the first guide rod, the first guide rod passes through the two connecting frames on the front side, and the rear side of the lower supporting base is rotatably provided with a bidirectional screw, which is threadedly connected to the two connecting frames on the rear side.

[0007] Furthermore, it also includes a motor, a connecting rod, a bevel gear set, a mounting seat, a screw rod and a second guide rod.

[0008] Furthermore, it also includes a support frame, a limit plate, a third guide rod, an elastic member and a counterweight. A support frame is arranged on the outside of the lower support base, and multiple third guide rods are fixedly connected to the support frame. A limit plate is slidingly arranged on the multiple third guide rods. An elastic member is sleeved on the third guide rod, and both ends of the elastic member are respectively connected to the limit plate and the third guide rod, and multiple counterweights are placed on the support frame.

[0009] Furthermore, a protective sleeve is included. The third guide rod is covered with the protective sleeve, and the elastic member is located in the protective sleeve.

[0010] Furthermore, it also includes an anti-wear pad, and the bottom of the support plate is embedded with an anti-wear pad.

[0011] Furthermore, it also includes a protective shell, and the motor is covered with the protective shell.

[0012] Compared with the existing technology, the utility model provides a robot welding machine base structure with the following beneficial effects: 1.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: A robot welding machine base structure, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 , including a lower support base 1, a support plate 2 and an upper support base 6. Two support plates 2 are slidingly arranged inside the lower support base 1. Slide grooves are opened on the front and rear sides of the support base 1. The support plate 2 slides in the slide grooves. An upper support base 6 is slidingly arranged on the lower support base 1. The front and rear sides of the support plate 2 are fixedly connected with connecting frames 3. The front side of the lower support base 1 is fixedly connected with a first guide rod 5. The first guide rod 5 passes through the two connecting frames 3 on the front side. A bidirectional screw 4 is rotatably arranged on the rear side of the lower support bottom. The bidirectional screw 4 is threadedly connected to the two connecting frames 3 on the rear side. An anti-wear pad 19 is embedded in the bottom of the support plate 2. The anti-wear pad 19 protects the bottom of the support plate 2, thereby avoiding wear on the support plate 2 when it is unfolded and retracted.

[0024] When the robot welding machine needs to be installed, first move the lower support base 1 to the appropriate position. Then, by turning the bidirectional screw 4, the connecting frame 3 drives the support plate 2 to move outward and unfold. Then, insert the bolts into the mounting holes on the lower support base 1 and the support plate 2, and use tools to tighten the bolts to fix the lower support base 1 and the support plate 2 to the operating table or the ground. In this way, the force-bearing area is expanded, which can increase the overall stability and prevent the lower support base 1 from loosening during long-term operation of the robot welding machine. Finally, move the robot welding machine to the support base and repeat the above fixing steps to install the robot welding machine on the upper support base 6.

[0025] Example 2: Based on Example 1, please refer to Figure 4 and Figure 5 A motor 7 is provided on the right side of the lower support base 1 by means of bolt connection. The output shaft of the motor 7 is connected to a connecting rod 8 through a coupling. A mounting seat 10 is installed inside the lower support base 1. The mounting seat 10 and the connecting rod 8 are jointly provided with a bevel gear set 9. A screw rod 11 is provided inside the upper support base 6 by means of bolt connection. A second guide rod 12 is provided inside the upper support base 6 by means of bolt connection. The screw rod 11 is threadedly connected to the bevel gear set 9, and the screw rod 11 and the second guide rod 12 both slide inside the lower support base 1. A protective shell 20 is covered on the motor 7, which protects the motor 7 to prevent damage to the motor 7 caused by external factors.

[0026] When the height of the base structure needs to be adjusted, start the motor 7, the output shaft of the motor 7 rotates to drive the connecting rod 8 to rotate, and the connecting rod 8 rotates to drive the bevel gear set 9 to rotate, so that the gear set rotates to drive the screw 11 to drive the upper support base 6 to rise, and then adjust the height of the base structure to suit different working scenarios. After adjusting the base structure to the appropriate height, turn off the motor 7.

[0027] See also Figure 1 and Figure 6 A support frame 13 is provided on the outside of the lower support base 1, and four third guide rods 15 are fixedly connected to the support frame 13. A limit plate 14 is slidingly provided on the four third guide rods 15. An elastic member 16 is sleeved on the third guide rod 15, and the two ends of the elastic member 16 are respectively connected to the limit plate 14 and the third guide rod 15. Four counterweights 17 are placed on the support frame 13, and a protective cover 18 is sleeved on the third guide rod 15. The elastic member 16 is located in the protective cover 18, thereby protecting the elastic member 16 to prevent foreign matter from being entangled on the elastic member 16.

[0028] After the lower support base 1 is fixed, the limit plate 14 is pulled upward so that it no longer blocks the support frame 13. At this time, the elastic member 16 will be compressed. Then, the counterweight block 17 is placed on the support frame 13 to increase the weight of the entire base structure to prevent the robot welding machine from tipping over due to the loosening of the lower support base 1. After placement, the limit plate 14 is released, and the elastic member 16 rebounds to move the limit plate 14 downward and reset, re-blocking the support frame 13.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
